Abstract:
Objective To analyze the related risk factors for Lisfranc injury resulting from low energy violence.Methods A retrospective study was performed for 61 cases (35 males,26 females) with low-energy foot injury hospitalized from June 2008 to June 2014.Mean age was 36.7 years (range,16-57 years).Fall injuries were noted in 24 cases,sports injuries in 21 cases,and twist injuries in 16 cases.The cases were divided into Lisfranc injury group(n =23) and non-Lisfranc injury group (n =38) according to the different diagnosis.Univariate analysis and multi-factor logistic regression analysis were used to identify the factors that may lead to the occurrence of Lisfranc injury including age,gender,body mass index,operation history,smoking,alcohol abuse,injury reason,medial depth of the mortise/ second metatarsal length (b/a),lateral depth of the mortise/ second metatarsal length (c/a),first metatarsal-to-talus angle,first intermetatarsal angle,second metatarsal length/foot length(a/g),calcaneal inclination angle and cuboid-navicular overlap/cuboid vertical height (e/e + f).Results Univariate analysis showed between-group differences were significant in age (x2 =7.385,P ＜0.05),injury reason (x2 =8.663,P ＜ 0.05),calcaneal inclination angle (t =3.958,P ＜ 0.05),b/a (t =5.051,P ＜ 0.05) and a/g(t =4.618,P ＜ 0.05).Logistic regression analysis identified b/a(OR =1.036,95 ％ CI 0.018-0.450,P ＜ 0.01) and a/g(OR =1.013,95％ CI 0.005-0.374,P ＜ 0.01) as independent risk factors for low-energy Lisfranc injury.Conclusion Low-energy Lisfranc injury is independently associated with b/a and a/g,and may relate to the decreased medial depth of the mortise and increased foot length.
